METHOD AND SYSTEM FOR CONTROLLING A VEHICLE POWERTRAIN BASED UPON ACTUAL VEHICLE LOAD
First Claim
Patent Images
1. A method for controlling vehicle powertrain comprising an electronically controlled engine with an ECM with memory, based upon actual vehicle load, comprising:
- determining the actual vehicle weight as vehicle load;
transmitting said vehicle load over a digital communication link for receipt by various vehicle powertrain components;
modifying engine operating parameters based upon the actual vehicle load;
transmitting messages regarding said modified engine operating parameters over said digital communication link to be received by powertrain components thereby changing operation of said powertrain components based upon said messages.

10. A vehicle system for controlling a vehicle powertrain based upon actual vehicle load, said vehicle having at least one wheel and axle, comprising
a vehicle powertrain comprised of an electronically controlled engine having a controller with operating software and memory, a clutch, a transmission with a electronic control unit (ECU) having transmission operating software and memory, and a computer area network (CAN) for communication of data signals to all powertrain components; - and
at least one sensor in close proximity to said at least one vehicle axle to generate data signals indicative of actual vehicle weight for transmission over said digital communication link to said engine controller, said engine controller responsive to vehicle load data signals to modify engine operating parameters based upon vehicle load. - View Dependent Claims (11, 12, 13, 14, 15, 16)
